"This last week I saw something that was breathtaking, a candidate--a former secretary of state who was campaigning in Massachusetts--where she said that 'don't let them tell you that businesses create jobs,'" Bush said as the audience booed. "Well the problem in America today is that not enough jobs are being created, (but) they are created by business."

The former governor was speaking during a campaign stop in Colorado on behalf of Republican candidates in the state's midterms.

"Don't let anybody tell you that it's corporations and businesses that create jobs," she said, critiquing the Republican economic platform. "You know that old theory, trickle-down economics. That has been tried, that has failed. It has failed rather spectacularly."

Clinton later said she "short-handed" the point she was trying to make.

"Let me be absolutely clear about what I've been saying for a couple decades," she said during a campaign event on Monday in New York. "Our economy grows when businesses and entrepreneurs create good-paying jobs here in an America where workers and families are empowered to build from the bottom up and the middle out, not when we hand out tax breaks for corporations that outsource jobs or stash their profits overseas."
